Installation The wheels are not fitted and have to be inserted into the housing. Remove accessories possibly stowed in the reservoir. Unlock the container locking system and remove motor housing. Remove all parts from the collection container, refit and lock the motor housing. Connect the suction hose to the intake distributor. Fit the extension tubes and slide on the supplied nozzle.

To facilitate transport, the transport brace can be changed by loosening the hand screw. The brace can then be hinged down for storage.

Install the Pondovac 3 at water level and at a minimum distance of 2 meters from the pond's edge. Make sure the unit stands safely.

Start Up
Connect the unit to the power supply. The unit is equipped with 2-position main switch.

Position I: Automatic Mode. Continuous vacuum cleaning and discharge.
Position O: The unit is switched OFF.

Use as sludge remover
Attention: Never operate the unit without foam filter or float switch.
Insert the drain hose in the rear outlet opening of the collection container. The unit automatically switches to vacuum cleaning and discharge. Vacuum cleaning is continuous. The unit discharges continuously through the outlet. Make sure the hose is laying flat and the drain hose is placed on a slight decline to allow gravity to help with drainage. Avoid kinks, bends, and uneven ground to ensure sludge water can drain freely. Dispose of the sludge in accordance to local regulations. At end of work, switch the unit OFF at the main switch.

Use as a Wet Vacuum Cleaner
Attention: Never vacuum dust or dirt. The filter is only suitable for fluids.
Replace the drain hose and cover the outlet drain with the enclosed closing plug.

Maintenance and Cleaning
Switch the unit OFF with the main switch and pull the power plug. Remove all hoses and the motor housing. Turn the inlet distributor out of the bayonet closure and if required, remove the inner reservoir (collection container) from the holder. Thoroughly rinse the collection container to remove all dirt particles. This also applies to the inlet distributor and the outlet valve.

Remove the foam filter by unbolting the engagement plates and washout with clean water. Check the foam filter and replace with original OASE foam filter. Check sealing rings for damage and completeness. If necessary, change the rubber seals in the inlet distributor and in the drain valve.

Empty out the collection container and clean the unit. Store in a dry, frost protected room inaccessible to children.
